Shaun - Taking photo's of the wheel to compare different anodize techniques should be treated like an experiment. Control the variables as best you can. This would include the back ground used, the lighting used, the angle the light hits the object, the camera angle relative to the object and lighting, all camera settings (ISO, aperture, shutter speed), even the distance from the object too.
Once you can get images with all those parameters the same, as much as possible, then you'll be able to really see differences in the anodize formula used.
Just my opinion from out here in the cheap seat in CA.
